Nathan k5la washington state

I have GMC Sierra 2500hd with Nathan airchime k5la. 2 viar 444c air compressors. 5 gallon tank. Ive owned truck for two years everything has been installed in truck for 5 years. The wiring is falling apart. Too much junk on the roads in the winter and I’m snowmobiling so in the snow a lot. Anyway compressors work but horn quit. What I’m looking for is if anyone is anywhere close to Seattle area. I would like someone to just replace all wiring for me. Have cash just not time also have never wired a horn set up before.

Any help is appreciated

My suggestion is to use marine wiring and connectors, instead of automotive-grade.

Also, use adhesive-lined heat shrink tubing, starting w/ the LARGEST size that will shrink to fit, so LOTS of adhesive goo oozes out of the ends, protecting the wiring from moisture.

Also, use sheathing, like split loom and anchor the wiring , w/ Adel clamps or w/ wire ties w/ anchors.
